COP FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 476,436, dated June '7, 1892.

Application tiled February l0, 1892. Serial No. 420,947. (Model.)

To all whom t may concern:

Be it known that I, CHARLES E. WILKIN- SON, of New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Cops for Sewing-Machines, of which the following is a specification.

My invention relates to an improvement'in cops for use in sewing-machines, and more particularly in cops for use in connection with open-sided shuttles-such, for example, as the oscillating shuttle of the Singer sewing-machine.

The object is to provide for the free rendering of the thread from the central portion of the cop between the cop and a temporary cover without liability of chafing or becoming tangled.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure l represents a cop in position in an oscillating shuttle of a Singer machine. Fig. 2 is a View ot' the cop in detail with its covers secured thereto. Fig. 3 is a view of the cop with its covers removed.

The shuttle is denoted by A, the cop by B, and its case by C.

XVhere an open-sided shuttle-such as is illustrated in the accompanying drawings-is employed, it becomes of importance to hold the cop of thread between covers, Which will prevent it from collapsing in whole or in part and will cause the thread to be unwound from the central portion of the cop in regular order. It is also desirable that the covers so employed should be simple and cheap, so that they may be furnished with the cop and thrown away after the cop is used. The covers may be formed of any thin paper or paper-board, or, in fact, of any material which will form a'thin layer over the side of the cop, and may be secured to the side of the cop by an adhesive material, preferably an adhesive which will not be liable to become hard and crack. Beeswax would answer the purpose well. I iind that paraine-paper makes a good cover. Between the inner face of the temporary cover C and the side of the cop Ii, I provide a radial channel b, leading from the central portion of the cop to its outer edge. The channel b is formed by indenting the side of the cop, as shown in Fig. 3. Along the channel `formed between the cover and the side of the cop the thread passes as it is being unwound from the interior of the cop without being forced to press upon and saw across either the edge of the cover or the outer threads of the cop, while the cop is held against any liability of collapsing until it is completely used. The cover completely protects the sides of the cop from dust and soiling and may be applied with great facility.

The indentation in the cop itself may be made by submitting the cop to pressure between two surfaces, one of which is provided with a rib corresponding to the indentation desired.

What I claim isl. A cop of thread having a channel indented therein, extending from its central portion outwardly, substantially as set forth.

2. A cop of thread having a radial channel indented in its side and a cover attached to the side of the cop and covering the channel, substantially as set forth.
